Abstract: Background/Objectives: Ultrasound-guided carpal tunnel release (UGCTR) has emerged as a minimally invasive alternative to open surgery for the treatment of carpal tunnel syndrome (CTS). This study aimed to evaluate the clinical outcomes, complication rates, and recovery profiles associated with UGCTR in a large multicenter cohort. Methods: A retrospective observational study was conducted across Italian hand surgery centers, including 735 patients who underwent UGCTR between January 2012 and April 2025. Data were collected on demographics, comorbidities, ultrasound measurements, and surgical outcomes. Primary endpoints included pain (measured using the Visual Analog Scale [VAS]), symptom severity and function (assessed via the Boston Carpal Tunnel Questionnaire [BCTQ]), complication rates, time to return to daily activities (RDA), and return to work (RTW). Follow-up assessments were performed at 1, 4, and 12 weeks postoperatively. Results: A significant improvement in pain was observed, with mean VAS scores decreasing from 6.37 preoperatively to 0.58 at 12 weeks. The mean cross-sectional area (CSA) of the median nerve decreased from 12.81 mm2 to 8.83 mm2 at 4 weeks. Both the BCTQ Symptom Severity Scale (BCTQ-SS) and Functional Status Scale (BCTQ-FS) scores showed significant improvement by week 1. The mean RDA was 5.7 days, and RTW was 14.5 days. Complication rates were low and decreasing over time, from 8.7% at 1 week to 3.4% at 12 weeks. Conclusions: UGCTR is a safe and effective technique for the treatment of CTS, offering rapid functional recovery and a favorable complication profile. Its feasibility in outpatient settings and potential for cost-effectiveness support its role as a viable alternative to open surgery and as a model of image-guided, minimally invasive intervention.
